|Route outline (key)|
The B3335 starts off at a roundabout where the A335 follows a modern single-carriageway bypass up to the M3 at junction 12. Our route heads northeast instead, passing underneath the main Southampton – Winchester line, and runs along the Itchen flood plain around Colden Common. There's a TOTSO with the B3354, just before the road enters Twyford. It passes through the middle of the village at a set of lights, which can cause queues. Then it's back out the other side and up to the north-facing sliproads of junction 11 of the M3.
The original straight ahead route up Five Bridges Road was sealed off when the Hockley Interchange was replaced by chopping a chunk out of Twyford Down, so instead there's a "useless multiplex" with the A3090 (which starts here) past the junction's south-facing sliproads up to St Cross Road. Then it's a few straight miles through suburban Winchester before terminating at traffic lights on the B3040 High Street at Southgate.
The B3335 dates to the 1990s and consists entirely of downgraded roads.
The Colden Common - Hockley section was originally the A333.
The run along St Cross Road was originally the A33. After the arrival of the Winchester Bypass, it became an extension of the A34 (which met the A33 near Shawford at a junction that no longer exists). When the A34 Winchester Northern Bypass was built in the late 1960s, the road became an extension of the A333, before becoming the latest route to gain the B3335 number when all remaining A roads in Winchester were downgraded post Twyford Down.
